Revival (부흥) - HyeonWon Ko

It is slow and intermediate A key song and lyric is really blessing. But also at the same time, it's pretty confusing to differentiate with the song "Vision" So you should mainly focus on lyric. 

Do not repeat the same melody just because its the same chord. Try to play it more melodically. Also take a close look at ad-libs. Ad-libs can't be done well in a moment, and if you practice while looking at the music, you can gradually immerse yourself in the music. Play it to the point where you can memorize it. 

Have a nice weekend.
